The designation is awarded to companies that have at least doubled revenue over four years, delivered a positive operating result every year, and avoided negative growth in the period. Fewer than one percent of Norwegian limited companies qualify. This is the second time SustEvo has earned the distinction. Growth is driven by increased demand for energy management in commercial real estate, new regional offices, and expansion into the German market. - [Gazelle Company 2024](https://sustevo.com/en/news/gazelle-2024): SustEvo qualifies as a Gazelle company for the first time, following four years in which revenue more than doubled and profitability was sustained. --- Dagens Næringsliv’s Gazelle Award recognises companies that, over four financial years, have more than doubled revenue, delivered a positive operating result each year, and avoided any decline. SustEvo meets the criteria for the first time in 2024. The growth reflects significant expansion of the client portfolio, the opening of regional offices in Northern Norway and Western Norway, and rising demand for energy management and reporting services. - [New office in Bergen](https://sustevo.com/en/news/new-office-bergen): SustEvo has opened a branch at Bryggen, led by Lars-Erik Lunde, to be closer to a growing client portfolio in Western Norway. SustEvo has opened a new office in Bergen. The premises are on Bryggen, and the office will be led by Lars-Erik Lunde. The move responds to growing demand from property owners in Western Norway for a local presence in energy management and operations optimisation. With an office in Bergen, travel time to buildings in Hordaland and Sogn og Fjordane is reduced, enabling technicians to carry out inspections and follow-up more quickly. The office will be staffed with advisors and operations engineers during the year. - [2024 in Numbers — A Look Back](https://sustevo.com/en/news/year-in-review-2024): A year of new offices, a larger project portfolio, and measurable client results — a brief recap. 2024 was a year of growth and consolidation. New regional offices in Bodø and Haugesund bring our consultants closer to clients, and we moved our head office to larger premises at Lysaker early in the year. Our project portfolio expanded across commercial real estate, hotel and industrial sectors. Several clients achieved double-digit reductions in energy use through systematic operational follow-up. The late-year launch of the SustEvo Dashboard gives portfolio clients real-time insight into consumption and climate data. We thank our clients, partners and colleagues for the past year. - [Introducing the SustEvo Dashboard](https://sustevo.com/en/news/dashboard-launch): A new dashboard gives customers real-time visibility into energy and climate data across the entire property portfolio. SustEvo Dashboard consolidates energy consumption and climate data from customers' buildings into one interface. It connects to meters, central operations control, and billing systems, and provides a portfolio view alongside detailed breakdowns by building, energy carrier, and time period. For property owners with many buildings, this enables faster detection of deviations, simpler reporting against the Taxonomy and CSRD, and a shared basis for operational and management decisions. The dashboard was developed with selected pilot customers throughout 2024 and is now being rolled out widely. - [SustEvo extends its international collaboration with Marriott](https://sustevo.com/en/news/marriott-partnership): SustEvo expands its partnership with Marriott across additional regions and will deliver energy management and operational optimisation for new hotels. The collaboration with Marriott is expanding to cover hotels across multiple European regions. Following strong results on Nordic properties, the partnership now includes additional assets within the group’s continental portfolios. In hotel operations, energy use is closely tied to occupancy, weather, and guest comfort. SustEvo works with local technical teams to fine-tune operating parameters to protect the guest experience, and to capture the outcomes in ongoing reporting. - [Surplus heat: turning waste into a resource](https://sustevo.com/en/news/excess-heat-recovery): Norwegian industry and data centres generate substantial waste heat. Recovering it can lower both costs and emissions. Much of Norwegian industry releases low-temperature heat that can be recovered. The same holds for data centres, where cooling loads generate heat well suited to local distribution to commercial buildings, residential areas, or process industries. The technology is proven. The tougher challenges are usually proximity between source and off-taker, clear contracts for delivery and pricing, and heat-pump designs that lift temperatures to usable levels. Several Norwegian projects show that payback can be short when government support, CO2 pricing and local district heating networks are in place. SustEvo helps industrial clients map opportunities and design such solutions. - [Takeaways from COP29 in Baku](https://sustevo.com/en/news/cop29-azerbaijan): The climate summit in Azerbaijan delivered modest progress on finance, but signalled moves with direct implications for the European building stock. COP29 was, in essence, a financing summit. Parties agreed a new framework for climate finance from rich to developing countries, but many observers view the level as too low to keep the Paris Agreement targets within reach. For European real estate, the indirect effects matter most. Stronger pressure on national climate plans will likely shape the pace of implementation of the EU Buildings Directive, carbon limits for building materials, and EU Taxonomy criteria. Norwegian owners of commercial buildings in Europe should track developments closely, particularly regarding requirements for renovation rates and documentation of energy performance. - [New energy mapping rules for large enterprises](https://sustevo.com/en/news/energy-mapping-regulation): A tightened energy management regulation broadens which companies must map their energy use — with a deadline in 2026. The government has announced amendments to the energy mapping regulation for large companies. The scope is broadened, bringing more companies under the requirement to systematically review energy use and identify cost‑effective measures. Companies with an ISO 50001‑certified energy management system will largely meet the documentation requirements. Others must complete the mapping by the new deadline and report the results. We recommend affected companies confirm their status early, both to ensure compliance and to use the mapping as a basis for concrete action. - [Hot water heaters for grid balancing](https://sustevo.com/en/news/power-balancing-water): Hot water heaters and accumulator tanks can act as flexible thermal storage, shifting load off the grid at peak times. The grid is under the most strain on cold mornings and in the early evening. Meanwhile, hot water heaters and buffer tanks across the country hold substantial thermal energy. By running heating outside peak periods, demand can be shifted without users noticing. For commercial buildings and larger residential properties, the potential is significant. Control can follow spot prices or capacity tariffs, sharing value between lower owner costs and reduced stress on the grid. Several Norwegian grid operators are now piloting flexibility markets that explicitly value this type of resource. - [Electricity support application deadlines are approaching](https://sustevo.com/en/news/power-support-deadline): Commercial buildings eligible for electricity support schemes and Enova grants should prepare applications well ahead of the deadline. Several current support schemes for commercial buildings are nearing their deadlines. This includes both Enova programmes aimed at energy measures and time‑limited compensation schemes from the authorities. Applications must document consumption, planned measures and expected impact. In our experience, assembling the documentation is the most time‑consuming step, especially for owners with many buildings. We recommend starting several weeks before the deadline to allow time for clarifications with the case officer. SustEvo supports clients with mapping and preparing application documentation. - [New Bodø office](https://sustevo.com/en/news/new-office-bodo): SustEvo has opened a regional office in Bodø and appointed Morten Hugvik Sandvik as Regional Manager North, strengthening on-the-ground follow-up across Nordland, Troms and Finnmark. SustEvo is opening a regional office in Bodø. Morten Hugvik Sandvik will serve as Regional Manager North, responsible for clients and projects in Nordland, Troms and Finnmark. Long distances in the north make a local presence important. From Bodø, our consultants and operations engineers can support clients faster with site visits, project kick-offs and ongoing follow-up. The office will scale staffing in line with the portfolio. - [SustEvo strengthens its presence in Western Norway](https://sustevo.com/en/news/new-office-haugesund): A new office in Haugesund brings SustEvo’s consultants closer to customers and buildings across the Haugalandet region. SustEvo opens a new office in Haugesund, reflecting a growing portfolio of projects across Haugalandet in both commercial property and industry. A local base makes it easier to conduct site inspections, coordinate with on-site technical teams, and follow up on measures over time. The office will work closely with our other Western Norway offices and central specialist teams. - [We are relocating our head office to Vollsveien 19](https://sustevo.com/en/news/oslo-office-move): SustEvo is consolidating its teams at new headquarters in Lysaker to support further growth. SustEvo is relocating its head office to Vollsveien 19 in Lysaker. The new premises bring consultants, operations engineers and support functions together under one roof and provide room for continued staffing growth. The premises are centrally located with good public transport access, and include meeting rooms and facilities designed to support closer collaboration between professional teams. The move is a natural next step after several years of growth in the Oslo team and across the regional offices. - [SustEvo opens German office in Frankfurt/Eschborn](https://sustevo.com/en/news/new-office-germany): SustEvo launches a German division, led by Winfried Baier, to meet rising demand from German real estate funds. SustEvo is launching a German division with an office in Eschborn, outside Frankfurt. Led by Winfried Baier, the team will support German real estate funds and portfolio owners with energy management, operational optimisation, and reporting. The move reflects sustained demand from German investors who already have parts of their portfolios in the Nordics under SustEvo’s oversight and want the same approach in their home market. The Eschborn office also creates a platform to serve other German‑speaking markets over time. - [New office in Tønsberg](https://sustevo.com/en/news/new-office-tonsberg): SustEvo opens a Tønsberg branch, appointing Ole Harald Neergård as branch manager to strengthen client support in Vestfold. SustEvo has opened a branch office in Sem, Tønsberg. Ole Harald Neergård will lead the office as branch manager, overseeing clients and projects in Vestfold and neighbouring areas. The move follows steady growth in the regional client base. A local presence enables faster site visits, focused assessments of improvement measures, and ongoing operational support. The office will work closely with the head office and other departments. ## Projects - [Gardermoen Flight Academy](https://sustevo.com/en/projects/gardermoen-flight-academy): New propane heat pumps for the training and simulator building, using a natural refrigerant with low GWP. ## The assignment CAE Oslo needed to upgrade heating and cooling for the training and simulator building at Gardermoen. Operational reliability was critical, and the refrigerant had to remain viable as regulations tighten. ## The result Propane heat pumps now provide heating and cooling with a natural refrigerant and very low GWP. The solution is resilient to upcoming F-gas requirements and delivers better energy performance than the previous installation. - [DEAS fund portfolio](https://sustevo.com/en/projects/deas-funds): EU Taxonomy assessment of a fund portfolio, covering classification, documentation, and a clear reporting basis. ## The assignment DEAS manages real estate funds whose investors expect clear EU Taxonomy reporting. SustEvo was engaged to assess the portfolio's buildings against the Taxonomy criteria and to establish a clear reporting basis. ## Result Each asset is classified for "substantial contribution" and "do no significant harm", with documentation and a gap analysis per building. The manager now has a consistent dataset for investor reporting and ongoing improvement. - [Grev Wedel Square 9](https://sustevo.com/en/projects/grev-wedels-plass-9): A comprehensive energy upgrade of a classic office building, achieving BREEAM In-Use Excellent. ## The assignment Grev Wedels plass 9 is a classic office building in central Oslo with strict constraints on technical interventions. Storebrand Eiendom sought to improve energy performance and certification without compromising the building's character. ## The result The plant room was rebuilt, controls upgraded, and operations formalised. Energy consumption fell by 60 %, and the building is now certified BREEAM In-Use Excellent. _The project was delivered by SustEvo staff at Rambøll._ - [Joh. Johannson Coffee Factory](https://sustevo.com/en/projects/joh-johannson-kaffefabrikk): New coffee factory designed around an energy-efficient process and certified BREEAM Excellent. ## The assignment Joh. Johannson Kaffe planned a new coffee factory in Vestby, aiming for high production quality and strong environmental performance. SustEvo supported the design, focusing on an energy-efficient process, heat recovery and BREEAM documentation. ## The result The factory recovers heat from the burner and cooling processes to cover a large share of its own heating demand. The building is certified BREEAM Excellent, and the operations team now has a facility that is simpler to run day to day. - [Hapro Electronics](https://sustevo.com/en/projects/hapro-electronics): Energy mapping and a full retrofit of the energy plant room delivered a 70 % cut in energy use. ## The assignment Hapro Electronics aimed to cut energy use and operating costs at its production facility in Jaren. SustEvo completed detailed energy mapping, identified the most effective measures, and engineered a full rebuild of the energy plant room. ## The result A new heat pump solution, process heat recovery, and upgraded controls have significantly reduced energy consumption. The building is more comfortable, the operations team has better oversight, and the payback period is short. - [JW Marriott Dubai](https://sustevo.com/en/projects/jw-marriott-dubai): Rapid operational optimisation delivered measurable reductions within two weeks of start-up. ## The assignment JW Marriott wanted an immediate impact on energy use without waiting for major investment projects. SustEvo carried out a focused review of ventilation, cooling, and controls, and prioritised measures that could be put in place straight away. ## The result Within two weeks of project start, several measures were in operation and delivered measurable reductions on the main meters. The guest experience remained unchanged, while energy consumption is lower and peak load has been reduced during the warmest period. - [Maersk Ålesund Cold Storage Facility](https://sustevo.com/en/projects/maersk-alesund-coldstorage): New cold storage facility designed fossil-free and certified BREEAM Excellent. ## The assignment Maersk planned a new cold storage facility in Ålesund with clear sustainability targets. SustEvo supported the design with a focus on the energy concept, refrigeration engineering, and BREEAM documentation, ensuring the ambition level was upheld throughout the process. ## The result The building was delivered without fossil fuels and is certified BREEAM Excellent. The refrigeration system uses natural refrigerants, recovers waste heat, and the energy performance is well below the reference requirements. - [DNV Høvik](https://sustevo.com/en/projects/dnv-hovik): Seawater heat‑pump solution at DNV’s headquarters providing low‑carbon heating and free cooling. ## The assignment DNV’s headquarters at Høvik set out to retire fossil peak‑load heating and adopt a reliable, low‑emission energy system. SustEvo engineered a seawater heat‑pump solution that supplies both heating and cooling, and integrated the delivery with the existing technical systems. ## The result The system is in operation, delivering stable heating and free cooling from the fjord. Operations are simpler, emissions from heating are effectively eliminated, and normal cooling demand is met without conventional chillers. - [Filipstad Quay](https://sustevo.com/en/projects/filipstad-brygge): Phase 1 achieved a 72 % energy reduction by refurbishing the energy plant room and optimising operations. ## The assignment Storebrand aimed to move Filipstad Brygge from average to leading in energy performance. SustEvo structured the work in phases, starting with the energy plant room and setting a plan to further optimise HVAC systems and controls. ## Results Phase 1 is complete and ahead of target. The upgraded energy plant room, paired with systematic operational optimisation, has cut energy use significantly while improving the indoor environment and operational stability. - [CRREM analysis in Denmark](https://sustevo.com/en/projects/crrem-denmark): A CRREM analysis of an office portfolio flagged assets at risk of stranding before 2030. ## The brief CBRE Denmark sought a clear view of climate risk across a large office portfolio. SustEvo conducted a CRREM analysis to identify which buildings are likely to become "stranded assets" under EU emissions pathways. ## The result The analysis gave the owner and asset manager a prioritized list of buildings needing action now, and a timeline showing when each asset would otherwise become stranded. The results provided a concrete basis for upcoming investment and sales decisions. - [Vestkanten Shopping Centre](https://sustevo.com/en/projects/vestkanten): A retrofitted energy plant room cut peak load and operating costs at the shopping centre. ## The assignment Vestkanten shopping centre was running an ageing heating and cooling system with high peak load and rising operating costs. SustEvo designed a retrofit of the energy plant room and, in parallel, laid the groundwork for better operations management. ## Result A new heat pump solution and upgraded controls now deliver year-round heating and cooling. Peak load is noticeably lower, operating costs are down, and the plant is easier to operate and maintain. - [Pynten Housing Cooperative](https://sustevo.com/en/projects/pynten-borettslag): Oil boiler replaced with an air-to-water heat pump, with Enova funding secured. ## The assignment Pynten Housing Cooperative sought to retire the old oil boiler and adopt a heating solution with stable costs over time. SustEvo reviewed the building stock, sized the new system, and managed the application process with Enova. ## The result An air-to-water heat pump now covers the majority of the heating demand, with electric backup for peak loads. Operating costs are lower, CO2 emissions from heating are effectively eliminated, and Enova funding significantly shortened the payback period. - [Nordea Majorstua](https://sustevo.com/en/projects/nordea-majorstua): Operational optimisation and an upgraded BMS/SCADA cut annual energy use by 2,9 GWh. ## The assignment Nordea's Majorstua office had complex technical systems and energy use out of proportion to the building's size. SustEvo was engaged to optimise operations, upgrade the BMS, and correct latent control faults. ## The result A systematic review of subsystems, new control strategies, and a BMS upgrade delivered a sustained reduction in energy use. The operations team now has better tools to keep consumption low year after year. ## Services — energy - [Energy audit](https://sustevo.com/en/services/energy/energy-mapping): Mandatory energy audit for large enterprises under the Energy Management Regulations. Large enterprises must carry out regular energy mapping. We deliver the mapping so it both fulfils the requirement and provides a solid basis for decisions. ## Contents - Review of energy use by building, process and energy carrier - Identification of measures with estimated savings and payback period - Prioritised list of measures ranked by profitability and climate impact - Report that meets the requirements of the Energy Management Regulations ## After the report - Basis for budgeting and investment decisions - Input for taxonomy and CSRD reporting - Basis for 3P-garantien or operational optimisation, where relevant The mapping is required every four years. We structure the work so the data can be reused — not just archived. - [Energy management](https://sustevo.com/en/services/energy/energy-management): Systematic reduction of energy use based on NS-EN ISO 50001. Energy management keeps consumption down in large property portfolios over time. We design and run the system to NS-EN ISO 50001. ## Key elements - Energy policy, targets and KPIs embedded in management - Target setting per building and for the portfolio, with a normalised baseline - Monthly variance reviews and corrective actions - Annual review and recalibration of targets ## Why it works Standalone measures deliver a one‑off effect. A system finds new deviations, follows measures through to operation, and builds organisational learning. Improvement becomes continuous, not project‑based. We can operate the system in the initial phase while training the internal organisation in parallel. - [Operational optimization](https://sustevo.com/en/services/energy/operational-optimization): Fine-tuning existing technical installations — typically 10–25 % lower consumption without investment. Most buildings consume more energy than necessary because their systems are out of tune. Operational optimization captures that gap before you invest in new technology. ## What we do - Review setpoints, operating hours and demand control - Analyse hourly consumption against operating schedules and outdoor temperature - Align ventilation, heating and cooling with actual use - Ongoing follow-up with monthly variance reports ## When it makes sense - Buildings with stable consumption that haven’t been reviewed in a few years - Portfolios with outsourced operations and no clear data ownership - A first step before larger measures — the savings simplify investment decisions We don’t deliver a single report and disappear. The impact lasts when the adjustments are maintained over time. ## When does it pay off? Operational optimization usually pays back faster than buying new technology, but some starting points yield particularly large gains: - Systems that are 3–5 years or older, where the original commissioning and tuning have drifted and setpoints have been changed over time without a consolidated overview - Buildings that have gone through pandemic periods or other long deviations in use, where operating patterns were never reset to normal operation - Properties with new tenants, changed usage profiles or refurbishments, where ventilation and heating still operate according to the previous use - Buildings with documented deviations between projected and measured consumption, or where energy management flags recurring deviations without an obvious cause - Portfolios where operations are fragmented across multiple providers and no one owns the energy data - [Retro-commissioning (RCx)](https://sustevo.com/en/services/energy/retro-commissioning): A systematic review and fine‑tuning of existing technical installations to ensure they perform as designed. Retro‑commissioning (RCx) is a structured way to return existing buildings to their intended performance. In practice, few installations run as designed — sequences get altered, sensors drift, and unnoticed losses accumulate. RCx identifies these deviations and corrects them. We offer three variants, matched to the building’s complexity, data access, and ambition. ## Full RCx Comprehensive optimisation for durable long‑term savings. - Mapping of all technical systems against the design intent - Functional testing of sequences, controls, and interactions - Measurement and verification of performance before and after - Detailed action plan with documented savings Best for complex buildings, portfolios with reporting requirements, or owners who want to evidence full performance over time. ## Light RCx (LRCx) Rapid diagnosis and immediate optimisation. - Walkthrough of central plantrooms and the BMS - Identification of the largest, quickest‑to‑implement measures - Short corrective actions delivered with the operations team Suitable for buildings that haven’t been reviewed for some time, where a short intervention yields immediate gains. Often the first step before deciding on Full or Tailored. ## Tailored RCx (TRCx) A customised blend of Full and Light, designed for the specific building or portfolio. - Focused on the systems with the greatest potential - Combines rapid diagnosis with deeper investigation where it matters - Adapted to the operations team’s capacity and the building’s operational phase ## After RCx - Documented performance against the design intent - Recommendations for energy management and continuous follow‑up - Basis for 3P-garantien, if relevant RCx is not a one‑off. We recommend a regular review — typically every three to five years — to prevent deviations from building up again. - [Energy advisory](https://sustevo.com/en/services/energy/energy-advisory): Pragmatic advice on energy sources, technical choices and strategic decisions across a building's lifecycle. Energy advisory is ongoing guidance — from selecting the energy source to assessing new solutions as they emerge. ## What we advise on - Energy source selection: ground-source heat, district heating, air-to-water, biofuel, hybrid solutions - Decision support for replacing the heating plant, ventilation or cooling systems - Evaluation and challenge of proposals from suppliers and contractors - Technical and financial analyses before investment - Strategic choices on electrification and capacity tariffs ## When it is appropriate - Early stage: before a project or tender is defined - Change of ownership or refinancing where the energy solution affects valuation - Ongoing support for operations or property teams needing an independent assessment We have no supplier ties. Our advice is impartial, and the goal is for you to make decisions with confidence — not for us to win the next project. - [Energy labelling](https://sustevo.com/en/services/energy/energy-labeling): Mandatory energy labelling for commercial buildings, including an energy certificate and a concrete list of measures. Energy labelling is required by law for commercial buildings over 1 000 m² and for any sale or lease. We deliver the energy certificate and determine the rating based on the building’s actual systems and operation. ## Deliverables - Survey and registration of the building - Energy calculation and determination of the energy rating - Energy certificate registered with Enova - List of measures with expected impact on rating and consumption ## When to do this - Before a sale or a new lease agreement - During renovation that alters energy performance - As a basis for further work on taxonomy or BREEAM The certificate is mandatory. The value lies in the measures list — and in using it to plan investments that can raise the building by one or two rating steps. - [Technical Due Diligence](https://sustevo.com/en/services/energy/technical-due-diligence): Technical due diligence focused on energy and sustainability risks in real estate transactions. Technical shortcomings get expensive after handover. Thorough due diligence surfaces risks while they can still be priced in—or negotiated out. ## What we assess - Condition of heating, ventilation, and cooling systems - Energy performance against a benchmark and the expected energy label rating - Alignment with the EU Taxonomy and the CRREM pathway - Required measures within 3, 5, and 10 years, with cost estimates - Risks from upcoming regulation (energy labelling, Taxonomy, climate requirements) ## Deliverables - Summary report with red/yellow/green status for each system and topic - Investment plan to reach the expected performance - Basis for pricing and negotiation - Input to a green CapEx plan or a decarbonisation roadmap ## When to use it - Purchase or sale of a single asset or a portfolio - Refinancing under green loan terms - Internal portfolio review as part of a fund strategy The report is concise enough for transactions, yet precise enough for the figures to stand up in negotiation. ## Services — engineering - [Energy plant room design](https://sustevo.com/en/services/engineering/energy-central-design): Engineering and design of heat pumps, borehole fields, district heating, free cooling and heat recovery. Experienced Norwegian specialists in energy plant room design. The energy plant room is the heart of a sustainable building. If it is designed poorly, the building pays for it for forty years. We design energy plant rooms that are simple to operate and flexible enough to handle changes in use and the energy market. ## Technologies - Heat pumps: ground-source, seawater, air-to-water, cascade - Borehole fields: sizing, balancing extraction and storage - District heating and district cooling integrated with on-site production - Free cooling from borehole fields, seawater or dry coolers - Heat recovery from internal processes, cooling systems, data centres and exhaust air ## Our role - Concept selection and preliminary design with life-cycle costs (LCC) - Detailed design of heating and cooling plants and control systems - Tender documents and contractor evaluation - Follow-up during construction and system balancing - Start-up, functional testing and handover ## What sets us apart - Experience from over one hundred energy plant rooms at various scales - Close collaboration with controls engineering — control sequences are not drawn up afterwards - Designed for operation, not the drawing board: we are on site when the plant is commissioned We can take responsibility for the full delivery, or act as a specialist resource alongside the general RIV designer. - [HVAC design (RIV)](https://sustevo.com/en/services/engineering/hvac-engineering): End‑to‑end HVAC and plumbing design — sanitary, heating, ventilation, cooling, sprinkler and pool systems. We provide end‑to‑end building services engineering (VVS/RIV) across the project lifecycle, from concept design to handover. ## Disciplines - Plumbing: water supply, drainage, roof drainage - Heating: low‑ and high‑temperature systems, distribution, heat emission - Ventilation: sizing, zoning, demand control - Cooling: process cooling, comfort cooling, free cooling - Sprinkler systems: hydraulic sizing and coordination with architect and fire safety - Pool engineering for swimming, therapy and spa pools ## Deliverables per phase - Concept and preliminary design, option selection and cost estimate - Detailed design: drawings, specifications and bill of quantities - Tender documentation and contracting support - Site follow‑up through construction and commissioning - As‑built documentation and operational handover ## Approach We design for operation first, aesthetics second. Systems that demand specialist competence are rarely operated correctly. Standardised solutions reduce energy use, cut operating costs and lower fault rates over time. We work across design‑build, client‑managed and collaborative contracts. Multidisciplinary coordination with automation and ITB is integrated, not an add‑on. - [Automation design (RIA)](https://sustevo.com/en/services/engineering/automation-engineering): SD systems, BMS, room control, control engineering, SCADA, and operational systems designed for real-world operation. A building with sound technical systems but poor automation will often use more energy than one with average systems and well-engineered automation. Automation ties the installations together — it deserves its own design, not an afterthought to the HVAC delivery. ## What we design - SD systems and BMS with full sequence descriptions, not just point lists - Room control for ventilation, heating, cooling, lighting, and solar shading - Control engineering: PI/PID design and tuning, cascade control, and demand-based strategies - SCADA and centralised operational monitoring for portfolios - Integration with energy metering, EOS, and portfolio-level ESG reporting ## Deliverables - Functional descriptions for each subsystem and system-to-system interactions - I/O lists, signal-flow diagrams, and control schematics - Tender documentation, evaluation, and verification of the supplier's application - Functional testing and follow-up through the operational phase ## Why it matters - 60–80 % of energy deviations in new buildings stem from automation faults, not the technical systems - Operators get a system that can be run without specialist expertise - Owners get a system that can feed data directly into ESG systems - [ITB coordination](https://sustevo.com/en/services/engineering/itb-coordination): Multidisciplinary coordination of HVAC, electrical, and building automation — so the building performs as designed at handover. ITB — integrated technical building installations — ensures disciplines coordinate and the final delivery is tested as one integrated system, not a set of isolated handovers. ## Our role - Coordinate RIV, RIE and RIA throughout the project - Clarify interfaces where responsibility is often unclear - Define checklists and documentation requirements per discipline and milestone - Develop test plans: component, integration and full system tests - Lead commissioning, functional testing and documented handover ## Phases 1. **Early phase**: requirements definition and cross-discipline descriptions 2. **Detailed design**: align drawings and functional specifications 3. **Construction**: follow-up across disciplines, review of suppliers' applications 4. **Commissioning**: testing, tuning and functional documentation 5. **Handover**: documented protocol, follow-up into the operational phase ## What it prevents - Systems that are well designed but not delivered as a coherent whole - Faults that surface in operation and are costly to fix - Disputes between contractors over interface responsibilities We can act as ITB lead for the client, or as a neutral coordinator for the main contractor. The goal is the same: documented, functioning systems from day one. - [Design verification](https://sustevo.com/en/services/engineering/design-verification): Independent verification of technical designs before construction — to catch errors while they are still inexpensive to fix. Design verification is a structured quality check of technical deliverables, performed by an independent specialist. ## What we check - Sizing against actual use and load profiles - Sequences, control loops, and interactions between systems - Consistency across system schematics, drawings, and specifications - Operability: can the system be run without specialist expertise? - LCC and LCA implications of the selected solutions ## Deliverables - Report with findings, prioritisation, and itemised recommendations - Direct dialogue with the design team to clarify and resolve issues - Final report documenting closure status ## When it is suitable - Complex projects with many interfaces - Clients without in-house technical capacity - As a second opinion before contracting or before construction start - Certification processes where independent verification is required We act as a technical counterpart, not a competitor. The goal is that what is delivered actually matches what was ordered. - [Engineering design](https://sustevo.com/en/services/engineering/project-planning): Technical design for energy systems, from requirements specification to tender documentation. We design technical systems that are buildable and operable. Our deliverable is the documentation contractors need to price and deliver the right solution. ## Disciplines - Heat pumps, energy centres, and cooling systems - BMS and automation - Solar PV systems - Ventilation and indoor climate ## Deliverables - Requirements specifications and performance descriptions - Design drawings and system schematics - Tender documentation and evaluation support - Construction-phase follow-up and verification against the design We bridge owner and contractor. Our goal is simple: what’s in the contract is what comes out of the building — without the owner needing to know every detail. ## Phases in a typical assignment - **Concept design**: map needs, load profiles, and boundary conditions. Assess concepts with high-level cost estimates and an energy budget to support decisions. - **Preliminary design**: select the primary solution with sizing, space requirements, LCC and LCA. Provide documentation detailed enough to give the client real cost certainty before detailed design. - **Detailed design**: final drawings, system diagrams, functional descriptions, bills of quantities, and technical specifications. Interdisciplinary coordination with architect, RIB, RIE, and automation. - **Tender documentation**: complete tender package with performance descriptions and evaluation criteria. We assist with contracting and quality-assure suppliers' bids. - **Construction follow-up**: verify against the design, clarify during construction, and participate in commissioning and functional testing through to documented handover. We tailor the scope to the project's complexity and contract model. On smaller assignments, phases are combined. On larger projects, clear decision points sit between each phase so the client retains control of cost, schedule, and technical content throughout. ## Services — execution - [Technical project management and ITB coordination](https://sustevo.com/en/services/execution/technical-project-management): Coordination of technical disciplines in construction projects, with documented handover of integrated systems. ITB — Integrated Technical Building Installation — makes sure HVAC, electrical and automation systems actually work together at handover. That integration does not happen on its own; someone must own the whole. ## Our role - Coordinate technical disciplines from start to finish - Clarify interfaces, especially around automation and BMS/SCADA systems - Plan tests, manage commissioning and run functional testing - Deliver a handover protocol with documented performance ## What it solves - Systems that are designed correctly but not configured as one integrated solution - Faults that only surface in operation and become expensive to fix - Unclear responsibility between contractor, supplier and the operations organisation We work for clients and for main contractors who need a neutral ITB resource. The goal is the same in either case: the building must deliver what was designed, from day one. Technical project management is more than chairing meetings. It requires the technical depth to challenge design choices, the experience to spot interfaces before they become conflicts, and the structure to ensure testing and documentation are completed. We take ownership of the entire technical delivery — from early sizing and room programmes, through design and procurement, to functional testing, training and warranty follow-up. The result is a predictable handover and a building that can be operated efficiently from day one. ## When is it used? - Complex technical renovation projects with many parallel trades and a high degree of interaction - New builds with a high level of energy and automation content where BMS/SCADA and control strategy are critical - Clients without in-house technical expertise who need a neutral technical lead - Projects with strict functional requirements for indoor climate, energy performance or requiring certification - Design-and-build contracts where the client wants independent ITB coordination across suppliers - [Construction management (BGL)](https://sustevo.com/en/services/execution/construction-management): On-site contractor supervision — quality control, progress tracking and handover inspection. Construction management is where design meets delivery. We are on site to verify that what was specified is built, so the client can take over a facility that performs. ## What we do - Track progress against the contracted schedule - Quality control of workmanship and supplied components - Checklists, non-conformance handling and change management - HMS and SHA follow-up in collaboration with project management - Plan and conduct the handover inspection - Follow up warranty claims throughout the warranty period ## Technical focus We bring deep expertise in HVAC, automation and energy systems — the areas where deviations are most frequent and most costly. We catch issues a generalist often misses. ## When it's appropriate - Clients who want tight control without staffing their own site team - Technical refurbishment projects - Energy systems, heat plants and other systems where commissioning and balancing are critical Construction management is not a formality. Rigorous follow-up pays back through fewer warranty claims, faster commissioning and lower energy use in the first year of operation. - [Owner's Representative (BHO)](https://sustevo.com/en/services/execution/client-representative): The client's representative for technical disciplines — coordinates consultants, oversees execution, and safeguards the owner's interests. The owner's representative is the owner's voice on the project. When the owner lacks in‑house technical capacity, we represent them from concept selection through to handover. ## Our role - The owner's technical representative to designers, contractors and suppliers - Coordinate consultants on the owner's behalf - Verify that proposed solutions meet the owner's actual needs - Provide decision support on concept selection, material choices and technology - Monitor budget, schedule and quality for the owner - Manage acceptance and handover, including technical documentation ## What it prevents - Decisions defaulting to the contractor's terms due to limited counter‑expertise - Design choices that are cheap to build but expensive to operate - Incomplete documentation at handover ## When it's appropriate - Property funds and family‑owned companies without an internal technical department - Housing cooperatives and condominium associations undertaking large‑scale refurbishments - Public clients requiring specialist technical expertise We have no supplier interests. Our recommendations are made in the owner's interest — even when that is inconvenient for the project. - [Design Management (PGL)](https://sustevo.com/en/services/execution/design-management): Leads and coordinates design consultants across disciplines throughout the project lifecycle. Design management keeps disciplines aligned from the first concept meeting through to completed tender documentation. Without clear leadership, disciplines pull in different directions, and interfaces become points of conflict rather than places for collaboration. ## Our role - Set up and chair design coordination across RIV, RIE, RIA, RIB, ARK - Define phase milestones, deliverables, and quality targets - Secure timely, documented cross-disciplinary decisions - Track delivery against agreed scope and quality - Coordinate with the client, project manager, and ITB ## Phases - Early phase: programming and concept selection - Schematic and preliminary design - Detailed design and tender documentation - Follow-up through construction and handover ## What it solves - Disciplines working in parallel without coordination - Inconsistent documentation at tender issue - Late changes caused by early decisions that were not anchored across disciplines We can lead the design team, or support the client's project manager. The goal is to deliver to the contractor a buildable, costed, and coordinated package. ## Services — sustainability - [Sustainability advisory](https://sustevo.com/en/services/sustainability/sustainability-advisory): Taxonomy, CSRD and CRREM analyses for real estate companies with mandatory reporting obligations. Reporting is no longer optional. We help real estate companies turn regulation into clear numbers, actions and decisions. ## What we deliver - EU Taxonomy: assessments of substantial contribution and DNSH for individual buildings and portfolios - CSRD: data foundations, materiality assessment and support for sustainability reporting - CRREM analyses: carbon risk and stranding year for each property - Decarbonisation roadmap with measures, costs and impact over time ## How we work We work with the real estate and finance teams, not beside them. Our analyses are practical enough to shape investment decisions—not sit as an appendix to the annual report. ## What we advise on - Materiality analysis: double materiality under CSRD, with stakeholder dialogue and documented prioritisation of topics that materially affect the company and its environment - CSRD implementation: gap analysis against ESRS, data collection, KPI structure and audit preparation — so the first reporting year is not a rush job - Taxonomy screening: assessment of substantial contribution, DNSH and minimum safeguards per asset and activity, with documentation that stands up to external review - Climate plan and roadmap to net-zero: measures, costs and emissions impact year by year, linked to the CapEx plan and financing options - ESG in investment decisions: embed sustainability criteria into due diligence, business cases and board decisions — so the numbers are actually used when acquisitions, disposals and refurbishments are considered - [BREEAM In-Use](https://sustevo.com/en/services/sustainability/breeam-in-use): Environmental certification for existing buildings, from baseline analysis to accredited submission. BREEAM In-Use is the leading standard for evidencing environmental performance in existing buildings. We manage the process from initial survey through to an approved certificate. ## Phases - Baseline assessment: your current score and a realistic target level - Action plan to reach Good, Very Good, Excellent, or Outstanding - Collection and structuring of documentation - Management of the application process with an accredited assessor ## What it's used for - Green financing and green bonds - Taxonomy documentation - Tenant requirements and leasing profile - Systematic improvement of operational and environmental performance We prioritise measures that add value beyond the certificate. Credits that are costly and offer little operational return are deprioritised. - [BREEAM New Construction](https://sustevo.com/en/services/sustainability/breeam-new-build): BREEAM consultancy for new-build and major refurbishment projects — from ambition setting to approved certificate. BREEAM-NOR is the reference standard for new construction and major refurbishments in Norway. We stay with the project from the first ambition meeting to the issued certificate, structuring the process so credits deliver real value in the building — not just on paper. ## Our role - Assessment of ambition level and early analysis of scoring potential - Strategy for which categories and issues to prioritise - Coordination with the design team and contractor throughout the project - Document collection, quality assurance and application preparation - Accredited AP or assessor role, or collaboration with an external assessor ## Certification levels We work with all levels — Pass, Good, Very Good, Excellent and Outstanding — and recommend an early, realistic assessment of which level delivers the best value for the building and the budget. ## What it is used for - Green financing and taxonomy documentation - Tenant requirements in the top tier of commercial real estate - Predictable environmental quality for long-term owners - A structured approach to operations and asset management We prioritise credits that deliver impact beyond the certificate. We advise against costly measures that add little in operation. - [EU Taxonomy screening](https://sustevo.com/en/services/sustainability/eu-taxonomy-screening): Portfolio assessment and reporting under the EU Taxonomy — substantial contribution, DNSH, and minimum safeguards per building. The EU Taxonomy sets a common definition of sustainable economic activity in the EU. In real estate, each asset can be classified against clear technical screening criteria — and that status affects reporting requirements, financing, and valuation. ## Our approach - Screening of individual assets against technical criteria (CCM 7.1, 7.2, 7.7) - Assessment of Do No Significant Harm (DNSH) for each relevant environmental objective - Check of minimum safeguards (social and governance) - Aggregation at portfolio and fund level - KPI calculation: share taxonomy-eligible and taxonomy-adjusted ## Deliverables - Per-asset report with classification and documentation trail - Portfolio-level compilation, ready for SFDR/CSRD reporting - Action packages to upgrade non-taxonomy-adjusted assets - Supporting documentation for green financing and bonds ## Who it's for - Real estate funds and managers with reporting obligations under SFDR - Real estate companies within the scope of CSRD - Banks and lenders requiring taxonomy documentation prior to lending Screening is not a one-off. We build methods and templates that let the company update status annually — without starting from scratch each time. - [CRREM analysis](https://sustevo.com/en/services/sustainability/crrem-analysis): Per-asset assessment of climate and stranded-asset risk against the 1,5- and 2-degree pathways. CRREM (Carbon Risk Real Estate Monitor) is the standard for gauging how long a property stays within a climate‑aligned emissions pathway. For owners and lenders, CRREM has become the practical language for transition risk. ## What the analysis delivers - Stranding year per asset: the point at which the building moves from within to outside the 1,5-degree pathway - Carbon intensity in kg CO2e/m2 benchmarked to the CRREM pathways - Portfolio summary and risk ranking - Measure packages that shift the stranding year, with cost and impact ## How it is used - Investment decisions and CapEx prioritisation - Reporting under SFDR, CSRD, and GRESB - Basis for green financing and green bonds - Fund‑level strategy and planning ## Our approach - Uses actual consumption data, not only modelled performance - Derives scope 1+2 emissions from each country's actual energy mix - Models the effect of planned and potential measures - Updated annually as part of ongoing ESG reporting - [LCA and LCC](https://sustevo.com/en/services/sustainability/lca-lcc): Life-cycle assessments for climate (LCA) and cost (LCC) — decision support for materials, technology choices and refurbishment versus new build. Life-cycle analyses let you compare options on the factors that matter over time: total environmental impact and total cost across the building's lifetime. ## LCA — life-cycle assessment for climate - Greenhouse-gas emissions calculated per phase (A1–A3, A4–A5, B1–B7, C1–C4) - Comparison of alternatives: materials, construction options, energy solutions - Input for BREEAM credits, taxonomy reporting and CSRD - Assessment of refurbishment versus demolition and new build ## LCC — life-cycle cost - Capital, operating, maintenance and end-of-life costs - Discounted net present value over the selected analysis period - Comparison of technical solutions with differing cost profiles - Sensitivity analysis for energy price, interest rate and service life ## Applications - Early-stage decisions where real alternatives exist - Portfolio-level refurbishment strategy - Decision support for heating plant, façade, ventilation or solar panels - Input for green financing and sustainability reporting These analyses add most value when done early — before the solution is locked in. We prioritise delivering quickly enough for the numbers to influence the decision. - [Climate risk](https://sustevo.com/en/services/sustainability/climate-risk): Physical and transition climate risk analysis at asset and portfolio level — aligned with TCFD and CSRD. Climate risk is no longer about if — but where and how much. We quantify both physical risks (weather, water, heat) and transition risks (regulation, market, technology) at the asset level. ## Physical risk - Exposure to flooding, sea-level rise, extreme precipitation, and surface water - Wildfire, landslide, and storm risk where relevant - Urban heat islands and cooling demand in urban contexts - Assessment of asset-level adaptation measures ## Transition risk - Exposure to forthcoming energy and climate regulation - Carbon price scenarios and impacts on operating costs - Market risk: tenant requirements and valuation impacts - Stranding year (CRREM) as an operational indicator ## Deliverables - Color-coded risk profiles at asset and portfolio level - Scenario analyses aligned with the TCFD framework - Adaptation plan with measures, costs, and prioritization - Reporting documentation for CSRD and SFDR ## Our approach We draw on established data sources (Klimaservicesenteret, EU Taxonomy screening, CRREM, international climate data providers) and link the analysis directly to each building's physical characteristics. The output is concrete enough to inform the CapEx plan — not just an appendix to the annual report. ## Services — performance - [3P-garantien](https://sustevo.com/en/services/performance/3p-guarantee): We guarantee measured reductions in energy use and take the risk if the measures do not deliver. 3P-garantien is SustEvo’s performance guarantee. We identify the measures, deliver them, and document the results. You pay only for the actual, measured reduction — nothing else. ## How it works - We survey the building and establish a baseline. - We define measures, budget, and expected savings. - We implement the measures and continuously monitor consumption. - If savings are not delivered, we cover the cost. ## What the customer gets - Predictable costs with no investment risk. - Documented consumption and climate impact for reporting. - A single provider accountable for the entire chain — from analysis to operations. The model suits owners who want to cut consumption quickly but prefer not to carry the technical implementation risk. 3P-garantien follows the principles of international energy performance contracts (EPC), tailored to the reality of Norwegian building owners. Unlike a traditional consulting engagement, responsibility shifts: we take both the technical and commercial risk that the measures deliver the promised savings. That means we perform a thorough pre-contract survey, select measures we can stand behind, and closely follow the installation after commissioning. In return, the building owner gets a predictable cost tied to actual performance, not to hours or deliverables. The model can be combined with Enova support and works for single buildings and portfolios that want to accelerate the energy transition without tying up internal capital or technical expertise. ## How the model works - Baseline measurement before measures: we establish a normalised reference consumption based on historical data, climate, and operational profile. - Guaranteed kWh and CO₂ reduction: the contract sets concrete targets for energy and emissions reduction. - Savings sharing or fixed price with risk sharing: the commercial model is adapted to the project, from pure gain-sharing to a fixed annual payment with bonus/malus. - Measurement and verification according to IPMVP: an independent methodology to document actual savings against the reference. - Duration 3–7 år: the contract period allows time to realise the effects of measures and adjust operations over several heating seasons. ## Services — digital - [Customer Portal](https://sustevo.com/en/services/digital/customer-portal): Customer portal for property portfolios — energy status, measures, and progress consolidated on app.sustevo.com. Customer Portal is SustEvo's portal for owners of larger portfolios. Available at app.sustevo.com, it gives a single view of energy status, measures in progress, and expected impact — without waiting for the next report. ## What you see - Energy status by building, aggregated and normalized for the portfolio - Planned and ongoing measures with responsible party and milestones - Expected and measured impact against baseline - Status reports, documentation, and deliverables linked to each project ## Who it's for - Property directors who need an overview without monthly meetings - Asset managers responsible for internal reporting - Customers with 3P-garanti or multi-year portfolio agreements ## Integrations - Pulls data from existing EOS and BMS systems - Combines it with data from SustEvo's own measurements - Exports key metrics for ESG reporting ## Access The portal is included in ongoing engagements. Users receive role- and portfolio-based access, and data is updated continuously from the sources we connect. Customer Portal runs on the same platform as our internal delivery management — so customers and our teams work from the same data foundation. - [Senviro](https://sustevo.com/en/services/digital/senviro): SaaS platform for ESG reporting and sustainability management — BREEAM, GRESB, CRREM, CSRD, SFDR and the EU Taxonomy in one system. Senviro is SustEvo's SaaS platform for sustainability management in the real estate sector. It unifies the requirements of BREEAM, GRESB, CRREM, CSRD, SFDR and the EU Taxonomy in a single data foundation — so figures are captured once and reused across frameworks. ## What the platform covers - EU Taxonomy: screening, DNSH, minimum safeguards - CRREM: stranding analysis for assets and portfolios - BREEAM In-Use: documentation and pre-assessment - GRESB: data collection and reporting - CSRD and SFDR: materiality, KPIs and report structure - Greenhouse gas accounting (scope 1+2, scope 3 where relevant) ## Data foundation - Pulls consumption data from existing EOS systems or directly from meters - Organises documentation at asset and portfolio level - Applies version control to reports and figures across years for audit traceability - Exports in formats requested by auditors and lenders ## Roles - Asset managers, ESG officers, operations, management — dedicated workspaces per role - Auditors and the finance department get access to underlying data and documentation ## Model Senviro is offered as a licensed product, often in combination with advisory services and an onboarding project. The platform can be used standalone, but delivers most value when tied to an ongoing advisory relationship that ensures data quality and use of the analyses. - [EMS and EOS support](https://sustevo.com/en/services/digital/ems-eos): Support with procuring, deploying, and operationalizing third-party energy monitoring and management systems. Energy and consumption data underpin all meaningful work on energy and sustainability. We help you select the right EMS or EOS, configure it so the data become usable, and embed it in day-to-day operations. ## What we do - Needs analysis and requirements specification for an EOS, EMS, or integrated platform - Market analysis and vendor evaluation - Procurement: negotiation, contracting, and delivery oversight - Commissioning: metering structure, data quality, normalization methods - Training for operations and property teams - Operational support during the initial operating phase ## Why it matters - Unstructured data are worthless — structured data form the basis for decisions - Incorrect metering structures prevent comparisons across buildings - An EOS that is not used costs more than it’s worth ## Vendor-neutral We have no ownership interests or agency agreements with EOS vendors. Recommendations are based on what best fits your portfolio’s size, complexity, and reporting needs. After implementation we are happy to continue working with the data — in energy management, operational optimization, or as the data foundation for Senviro and other reporting tools. ## Services — funding - [Enova funding applications](https://sustevo.com/en/services/funding/enova-applications): Preparation of applications and supporting documentation for Enova funding of energy and climate measures. Enova support can decide whether a measure is delivered or left on the shelf. We handle applications, documentation and reporting so the potential is realised. ## Programmes we work with - Energy measures in existing commercial buildings - Heating plants and energy flexibility - Innovative solutions and pilot projects - Surveys and feasibility studies ## Our role - Identifying the right programme for the project - Preparing the application with technical and financial documentation - Calculating expected impact and funding amount - Managing reporting and documentation during implementation and at completion ## What it requires - Early engagement: the earlier we are involved, the better we can shape the project to meet the criteria - Accurate data — Enova verifies calculations and assumptions - Commitment to document impact after implementation We work across a wide range of Enova programmes and understand case officers' thresholds for sufficient documentation. That lowers the risk of rejection and makes the process more predictable. - [Financing advisory](https://sustevo.com/en/services/funding/financing-advisory): Mapping national and international incentive programmes — Enova, BEG, KfW and equivalents — for energy and sustainability measures. The financing and incentives landscape is fragmented and moves fast. We identify what is truly available for your project and align measures with the programmes that deliver the strongest overall outcome. ## Programmes we track - Enova and Innovation Norway (Norway) - BEG (Bundesförderung für effiziente Gebäude) (Germany) - KfW financing for energy and rehabilitation measures - EU programmes: Innovation Fund, LIFE, Horizon Europe - Green loan terms from Nordic and European banks ## Our role - Map relevant programmes by geography and project type - Assess combinability — what can be stacked, what is mutually exclusive - Design a financing plan that blends multiple sources - Support applications directly or via local partners - Report and document achieved impact ## Who it's for - Real estate companies with cross-border portfolios - Industry and infrastructure planning large-scale energy measures - Investment decisions where support affects profitability We charge for the work, not a share of the support secured. Our advice is guided by what is best for the project, not what maximises our fee. ## Buildings - [Office building](https://sustevo.com/en/buildings/office): Data-driven operations and measurable reductions for modern offices with strict requirements for indoor environmental quality and tenant documentation. ## Typical challenges Many office buildings have robust technical systems that are underutilised. BMS are set up at commissioning and seldom tuned to real use. Ventilation runs at full capacity while half the space is empty, and heating and cooling push against each other. - Over-ventilation outside core hours - Legacy BMS without demand-based control - Poor coordination between heating and cooling - Tenant CSRD and EU Taxonomy requirements that demand verifiable figures ## What we deliver We review the operating strategy for ventilation, heating, cooling and lighting, and propose specific changes that can be implemented without major investment. If new meters, sensors or BMS upgrades are required, we define the scope. We also provide the documentation basis for EU Taxonomy and CSRD reporting. ## Outcomes - 10-25% reduction in energy use within the first year of operation - Stable indoor environmental quality with fewer complaints - Documentation that meets tenant requirements and supports reporting - More structured service agreements and clearer allocation of responsibilities - [Shopping centres and retail](https://sustevo.com/en/buildings/retail): Integrated energy management for shopping centres and retail assets with variable loads, multiple tenants, and a need for attractive common areas. ## Typical challenges Retail properties have large, fluctuating loads throughout the day and year. Refrigerated display cases release heat into common areas while the heating system works to compensate. Tenants keep different hours and run their own technical solutions, and the common areas must stay welcoming without energy costs spiralling. - Heating and cooling systems working against each other - Tenants operating independently with no coherent metering structure - Common areas requiring high lighting levels and ventilation throughout opening hours ## What we deliver We trace energy flows across tenant spaces, common areas and plant rooms, and pinpoint where heat recovery and coordinated control deliver the greatest effect. We review service agreements and the metering setup, and establish an operational strategy that works across tenants. Follow‑up is handled with clear KPIs and simple reporting to centre management. ## Outcomes - 15-25% reduction in common areas' energy use - Recovery of surplus heat from refrigeration units - Clearer cost allocation among tenants - Improved thermal comfort in common areas throughout the year - [Hotel](https://sustevo.com/en/buildings/hotel): Energy and operational optimization for hotels running 24/7, with tight comfort requirements and wide occupancy swings across the year. ## Typical challenges Hotels run 24/7 and cannot dial systems back when guests arrive. Hot water demand is high and uneven, and ventilation and room temperatures must stay within tight bounds. At the same time, occupancy varies widely between weekdays and weekends, seasons and holidays — the building must adapt without compromising the guest experience. - Ventilation and heating running continuously in unoccupied rooms - Significant, poorly mapped losses in hot-water distribution - Limited integration between PMS (occupancy) and building operations ## What we deliver We analyze consumption against actual occupancy and configure controls to match the hotel's rhythm. Hot-water production and circulation are reviewed for temperature levels, insulation, and heat recovery. We also support integration between the booking system and the BMS where it adds value. ## Outcomes - 10-20% reduction in total energy use - Lower hot-water consumption without compromising comfort - Stable indoor climate in rooms and common areas - Operational routines that handle seasonal variation - [Industry and logistics](https://sustevo.com/en/buildings/industrial): Energy and heat recovery for industrial, warehouse, and logistics buildings where process loads often dominate building energy use. ## Typical challenges In many industrial and logistics assets, process and cooling loads exceed the building’s own energy use by several multiples. Valuable waste heat is rejected while the heating system brings in new energy. Warehouses often ventilate and heat large volumes without demand control, and new logistics buildings increasingly face BREEAM requirements from tenants and investors. - Unrecovered process heat - Heat loss dominated by door openings and infiltration - Insufficient metering separating process and building operations ## What we deliver We map energy and heat flows across process and building operations, and pinpoint where heat recovery is technically viable and economically justified. For new buildings, we support BREEAM with energy calculations, documentation, and quality assurance. For existing facilities, we prioritise measures by payback period. ## Outcomes - Process heat recovered for space heating and domestic hot water - 15-30% reduction in building-related energy use - BREEAM credits for energy and monitoring - Measurement and reporting structure that separates process from building operations - [Condominiums and Housing Cooperatives](https://sustevo.com/en/buildings/residential): Decision support and implementation for condominiums and housing cooperatives switching heat source and lowering shared operating costs. ## Typical challenges Many condominiums and housing cooperatives run shared heating and domestic hot water systems on fossil fuels, and are now moving to heat pumps or district heating. Boards often have limited technical capacity, while residents need clear information and a predictable cost outlook. Enova support can be significant, but it depends on proper documentation and sequencing. - Ageing oil or electric boilers that must be phased out - Domestic hot water losses and uninsulated circulation pipes - The board must present the proposal at the general meeting ## What we deliver We give the board an independent basis for decision, with realistic cost estimates, expected savings, and Enova funding options. We support specifications, tendering, and construction‑phase follow‑up, and set up resident communications that keep the general meeting calm and efficient. ## Outcomes - 40-70% reduction in purchased energy for heating - Predictable common charges over time - Correct drawdown of Enova funding - Documentation and operating routines that withstand board turnover ## FAQ - [Choosing an energy consultant for commercial buildings](https://sustevo.com/en/faq/how-to-choose-an-energy-advisor): A practical checklist for property owners and portfolio managers — what to look for, what it costs, and the questions to ask before you sign. ### What does an energy adviser do? An energy adviser maps where energy is used in the building, identifies which measures are truly cost‑effective, and follows them through execution and operation. The difference between a good and a mediocre adviser is how much of the report turns into real savings. Always ask for references with measured results from delivered projects, not just a list of assignments. ### What does energy mapping cost? For a typical 5 000–10 000 m² office building, a thorough energy mapping usually costs between 80 000 and 200 000 NVA, including site inspection, data analysis and report. The price varies with complexity, number of technical systems, whether the building has existing EOS data, and whether the adviser will include profitability calculations or only meet the regulatory requirement. Always ask the quote to specify what is mandatory and what is extra. ### How long does the process take? From signed agreement to final report: typically 6–10 weeks. Site inspection and data collection take 1–2 weeks, analysis 3–5 weeks, and reporting and quality assurance 1–2 weeks. Measures from the report can be implemented immediately where conditions allow — for example operational optimisation — while investment measures are typically phased in over 12–36 months. ### What distinguishes a good adviser from the rest? Three clear signals to look for: 1. Measured results from delivered projects — kWh/m² before and after, not just percentages. 2. A multidisciplinary team (HVAC, building automation, sustainability) under the same roof, not subcontractors. 3. Willingness to enter performance‑based contracts — advisers who guarantee savings trust their numbers. Also look for certifications such as BREEAM AP, ISO 50001 auditor, and membership in Enova’s adviser network. ### Should the adviser and the contractor be the same party? It depends on project size. For energy mapping and initial strategy: no — independence protects against bias toward selling one’s own services. For retro‑commissioning, operational optimisation and energy plant room design: often yes, because the learning loop from implementation back into design is one of the most valuable parts of a project. Check that the adviser has clear procedures to avoid conflicts of interest when both roles are combined. ### What questions should I ask before I sign? Ask specifically for: 1. Three delivered projects with measured energy reductions (kWh and percent). 2. Who will actually do the work — named engineers, not just a company name. 3. How the adviser handles data from EOS, BMS and billing history. 4. Whether the quote includes profitability calculations and Enova applications, or if these cost extra. 5. Guarantees — what happens if the measures do not deliver as promised? ### Where do I find a qualified adviser? Enova publishes a list of advisers who have submitted approved Enova applications — a good starting point. Industry organisations such as Rådgivende Ingeniørers Forening (RIF) and NEMITEK have membership lists. For larger portfolios, we recommend pre‑qualifying 3–4 suppliers through a mini‑competition, testing them on a defined case building before awarding a framework agreement. - [Energy mapping for large enterprises — who is covered and when](https://sustevo.com/en/faq/energy-mapping-requirements): Who must carry out energy mapping in Norway, the energy threshold, the deadlines, and what the mapping must contain. ### Who must carry out energy mapping? The duty targets large enterprises and organisations with substantial energy use across their buildings and operations. It is independent of sector — offices, retail, industry, logistics and public bodies are all in scope if they pass the energy-use threshold. ### What is the energy threshold? The requirement applies to enterprises with an average annual energy use above 2.5 GWh in Norway. Energy use is assessed across the organisation's buildings, installations and transport, not per individual building. ### When did the requirement take effect and how often must it be repeated? The regulation took effect on 1 October 2024. Mapping must be carried out and then repeated at regular intervals — every four years — so the data and the measure list stay current rather than becoming a one-off archive document. ### What must the mapping contain? A compliant mapping reviews energy use by building, process and energy carrier, identifies cost-effective measures with estimated savings and payback, and presents a prioritised measure list. It should be detailed enough to support investment decisions, not just satisfy a formal duty. ### What happens if we do not comply? The mapping is a legal obligation for covered enterprises, and authorities can follow up non-compliance. Beyond the formal risk, skipping it means leaving documented, profitable savings on the table — most mappings identify measures that pay for the work several times over. ### How does SustEvo deliver it? We structure the mapping so the data can be reused for energy management (ISO 50001), CSRD and EU Taxonomy reporting, and Enova applications. The output is a prioritised, costed measure list with a clear baseline — a basis for action, not a report that gets filed away. - [Energy mapping, energy labelling and energy management — what is the difference?](https://sustevo.com/en/faq/mapping-vs-labeling-vs-management): Three terms that are often confused. What each one is, when you need it, and how they fit together. ### What is energy mapping? Energy mapping (energikartlegging) is a point-in-time survey of where and how a building or organisation uses energy, ending in a prioritised list of cost-effective measures with savings and payback. It is the diagnostic step — it tells you what to do. ### What is energy labelling (energimerking)? Energy labelling assigns the building an energy grade (A–G) and a heating grade, based on standardised calculation. It is typically required when a building is sold or let, and it communicates relative performance to the market — but it does not, by itself, produce a measure plan. ### What is energy management (ISO 50001)? Energy management is a continuous system — usually built on NS-EN ISO 50001 — for systematically reducing energy use over time, with a baseline, energy performance indicators (EnPIs), targets and regular follow-up. It is the operating model that keeps the savings from a mapping from eroding. ### Which one do we need? If you must comply with the energy mapping regulation, you need mapping. If you are selling or letting, you likely need labelling. If you want durable, year-on-year reductions across a portfolio, you need energy management. Most large owners need all three at different points. ### Can they be combined? Yes — and they should be. A mapping provides the baseline and measure list that feed an ISO 50001 system, and the resulting data strengthens the next labelling and supports CSRD and EU Taxonomy reporting. We design the work so each step feeds the next instead of being repeated. - [How to reduce energy use in commercial buildings without investment](https://sustevo.com/en/faq/reduce-energy-without-investment): Operational optimisation and retro-commissioning can cut 10–25% of energy use with little or no capital outlay. How it works and how the savings are verified. ### Is it really possible to cut energy use without investing? Yes. The systems are usually already installed; they are simply not tuned for how the building is actually used. Adjusting setpoints, schedules, control sequences and night/weekend operation typically recovers 10–25% of consumption without capital expenditure. ### What is operational optimisation? Operational optimisation is the systematic tuning of an existing building's technical systems — ventilation, heating, cooling and building automation (BMS/SCADA) — so they deliver the same or better indoor climate with less energy. It works from the building's own operating data. ### How much can we save? For a building that has not been optimised recently, 10–25% is a realistic range, with the upper end where controls have drifted or were never commissioned properly. Savings are largest in ventilation and heating, and they persist only if the building is kept in tune. ### What about retro-commissioning? Retro-commissioning is a structured process that brings an existing building back to — or beyond — its intended performance, finding and fixing faults in control logic, sensors and equipment. It is more thorough than a one-off optimisation and is the right tool when systems have degraded over years. ### How do you verify the savings? We establish a baseline from metering and EOS/BMS data before the work, then compare actual consumption afterwards, normalised for weather and occupancy. Reporting kWh/m² before and after — not just a percentage — is what separates a real result from a claim. - [ISO 50001 energy management in practice](https://sustevo.com/en/faq/iso-50001-in-practice): What NS-EN ISO 50001 is, whether you need certification, and how baseline, EnPIs and follow-up turn into durable savings. ### What is ISO 50001? ISO 50001 is a framework for systematically managing and reducing energy use. It sets up an energy policy, a baseline, measurable indicators, targets and a regular review cycle — the same plan-do-check-act loop as other management standards, applied to energy. ### Do we need certification? Not necessarily. Many owners adopt the ISO 50001 method to get the results without pursuing formal certification, while others certify because customers, lenders or reporting frameworks expect it. The savings come from the system, not the certificate. ### What is an energy baseline and EnPI? The energy baseline is the reference level of consumption against which future performance is measured, normalised for factors such as weather and occupancy. Energy performance indicators (EnPIs) — for example kWh/m² or kWh per production unit — track whether you are actually improving against that baseline. ### How long does implementation take? For a single building or a small portfolio, a working system is typically in place within a few months; embedding it into daily operations and seeing trended results takes a full operating year. The first year usually delivers the largest step change. ### What results can we expect? Combined with operational optimisation, an ISO 50001 system commonly sustains double-digit percentage reductions and, crucially, holds them — because deviations are caught and corrected through the review cycle rather than discovered years later. - [Heat pump, borehole field, district heating or hybrid — what should a building owner choose?](https://sustevo.com/en/faq/energy-plant-room-choices): The main options for a commercial building's energy plant room, when each one fits, and how to decide. ### What are the main options for a commercial building's energy plant room? The common building blocks are air- or water-source heat pumps, borehole (ground-source) fields, connection to district heating, and heat recovery — often combined with free cooling. Most well-designed plant rooms are a combination rather than a single technology. ### When is a heat pump the right choice? A heat pump is usually the backbone where you have a year-round or balanced heating and cooling demand and a suitable heat source — outdoor air, seawater, a borehole field or waste heat. It delivers low-carbon heating and, with the right design, free or low-cost cooling. ### When does a borehole field make sense? A borehole field suits buildings with both heating and cooling needs, where the ground can be used as a seasonal store — cooling in summer charges the ground with heat that is harvested in winter. It needs space for drilling and a load profile that balances over the year to stay efficient. ### Is district heating still a good option? Yes, where it is available and competitively priced. District heating removes the on-site plant and maintenance burden and can be very low-carbon depending on the source. The trade-off is less control over future tariffs and a weaker case for on-site free cooling. ### What is a hybrid solution? A hybrid combines technologies — for example a heat pump for base load with district heating or a boiler for peak load — to optimise cost, carbon and resilience. Sizing the heat pump for base load rather than peak is often the single biggest lever on both cost and emissions. ### How do you decide? The decision should follow the building's measured or modelled load profile, the available heat sources and space, the carbon and taxonomy ambitions, and lifecycle cost (LCC) — not just the lowest install price. We design the concept so it actually performs in operation, which is where most plant rooms underdeliver. ## Sitemap - XML sitemap: https://sustevo.com/sitemap.xml
